πŸ’Ž If you provide a price or quote best to leave out the comma (it makes the number look smaller)

To manipulate the number of syllables of a given price Coulter, Choi, and Monroe (2012) introduced a comma into the same four-digit price and let it mention in a radio commercial as, for example, $1,645 (one thousand six hundred forty-five: 9 syllables) vs. $1645 (sixteen forty-five: 5 syllables). Then participants were asked to rate the magnitude of the price on a 10-point scale.

Participants rated the magnitude of the price with the comma higher than the same price without a comma.
